This study examines the inscription of sound in Romeo Castellucci’s mise en scène of Inferno. It aims to define how the sound environment of this work goes beyond the traditional use of sound in theatre, and how its integration to the stage action creates a new type of dramaturgy. No more intended as the representation of a narrative, this work emphasizes and reinforces the materiality of any medium constituting the action. We will analyze how the sound in this performance becomes an element on its own. Sound is not mimetic anymore: it does not aim to be the echo of something absent. The sound being able to affirm and render its own expressive qualities, it can “interact” with other scenic elements in an innovative manner. The interactions of both visible and audible components give rise to dramaturgical tensions, conducting us to investigate the question of listening and its modalities in a theatrical context. We will then try to understand how audition redefines the reception of the performance.
